Utility-Scale Portable Energy Storage Systems

Energy Storage Technologies for Utility Scale Intermittent Renewable Energy Systems

In current conventional utility systems, fossil fuel or nuclear power plants must back up intermittent renewable electricity generators if the utility grid is to have acceptable reliability. For low levels of intermittent power, this can be achieved without difficulty or added expense. For high levels this reliance on other generators becomes explicit and increasingly expensive, and transmissio...

Integration and Operation of Utility-Scale Battery Energy Storage Systems: the EPFL’s Experience ?

The experimental integration and control of an utility-scale 720 kVA/500 kWh battery energy storage system (BESS) in the medium voltage network of the Swiss Federal Institute of Technology of Lausanne (EPFL) to achieve dispatched-by-design operation of a heterogeneous group of prosumers is discussed. The motivation for such an objective is twofold: (i) dispatching the operation of prosumers red...

Hydrogen-based Utility Energy Storage System

SRT Group, Inc. (SRT), a leader in innovative energy processes involving halogens, has developed and patented an innovative electrical energy storage and hydrogen production system. The SRT system stores off-peak electricity and produces hydrogen via a novel natural gas/steam thermo-electrochemical process. The following economic analysis indicates that the system can provide on-peak electrical...

Controllable and affordable utility-scale electricity from intermittent wind resources and compressed air energy storage (CAES)

World wind energy resources are substantial, and in many areas, such as the US and northern Europe, could in theory supply all of the electricity demand. However, the remote or challenging location (i.e. offshore) and especially the intermittent character of the wind resources present formidable barriers to utilization on the scale required by a modern industrial economy. All of these technical...
